The invention relates to the field of polymers, and discloses a polyester composition, a preparation method of the polyester composition, a heat shrinkable film and a preparation method thereof. Specifically, based on the total weight of each component, the polyester composition contains the following components: (1) 51-99% by weight of polyester A; (2) 1-49% by weight of polyester B. The heat shrinkable film made by using the polyester composition provided by the present invention can not only have a higher heat shrinkage rate, but also can change its heat shrinkage rate within a large range to meet different needs; The heat shrinkable film has suitable heat sealing strength, smooth surface, good gloss, degradable and can be repeatedly thermoplastic processed and recycled. |
